. To all whom it may concern:

Be it known that I, STEWART HARTsHoRN, a citizen of the United States ofAmerica, and a resident of Short I-Iills, county of Essex, and State ofNew Jersey, have invented a new and useful Means for Attaching Fabricsto Rollers, of which the following' is a specification.

My invention relates to improved means in attaching fabrics, such asshades, curtains, awnings, etc., to spring or other rollers.

The general object of the invention is to produce a device by means ofwhich the fabric may be attached to t-lie roller without the need oftools.

Further objects are to produce an arrangement wherein the roller willnot be `considered together or separately.

In the drawings, Figure 1 is a side elevation of a roller, and a portionof a fabric showing one embodiment of my invention with the fabric inthe first position. Fig. 2 is a similar view with the fabric in thesecond position. Fig. 3 is a section on the line 3 3 of Fig. l, on agreatly enlarged scale. Fig. 4 is a section on the line 4 4 of Fig. l.Fig. 5 is a section on the line 5 5 of Fig. 2. Fig. 6 is a perspectiveview of one form of fastener. Fig. 7 is a perspective view of amodification. Fig. 8 is a perspective view of another modification. Fig.9 is a side elevation of a portion of a shade roller showing anothermodification. Fig. l0 is a section on the line l0 10 of Fig. 9. Figs. l1and l2 are views of a detail of another modification. Fig. 13 is adetail view of still another modification.

In all of the views like parts are designated by the same referencecharacters.

In carrying out my invention I provide accompanying drawings as formedof sheet metal, but the invention is not limited to a roller of thiskind as it may be made of any material.

In the drawings, the roller l is shown as made of sheet metal, and isprovided with the usual pin and spear at the extremities, and with thespring and pawls (not shown), according to the well known I-Iartshornspring shade roller. Any other foi-m of roller, with or without aspring, niay be employed.

The roller shown in Figs. l to 5 inclusive, is made of a tube of sheetmetal, shaped to a cylindrical form with the edges overlapping. Theparts are secured together as by solder 2 (see Fig. 3), producing astraight edge 3, which extends the entire length of the inet-allieportion of the roller. The part of the sheet metal which lies within theouter surface of the roller is unsoldered and forms a flap 4. A portionof the outer surface of the roller above this flap is made in the formof an opening or slot 5. As shown in Fig. l, this slot is rectangular inshape. A plurality of these slots are formed upon the roller and extendthroughout its length. The number and shape of the slots may be variedas desired. The edge 6 of the slot which lies on the side toward thestraight edge 3 is at the extreme limit of the solder 2 which connectsthe edges of the metal plate together. It is not necessary, however,that the solder extend entirely from the straight edge 3 to the edge 6.The flap 4 is forced by its own elasticity and the elasticity of therest of the material of which the roller is made with elastic pressure against the other side of the opening 5, and against the edge 7. Thematerial of which the roller or the flap is made need not be elastic; inthis case the flap may be separated a suitable distance from the innerwall of the roller. The flap is not necessarily integral with the restof the roller. rI`he fabric 8, which may be a curtain, shade, awning orother device, is attached to the roller by means of fasteners 9, oneform being shown in Fig. 6. The fastener is of a general T shape shown,having al head or cross member l0 and a tyne 11 at right angles thereto.The tyne is curved in relation to the cross member, as shown, and itsend is pointed. This pointed end is adapted to be pushed through thefabric for thel purpose of securing the latter to the roller.

As shown in Fig. l, the fastener, of which a plurality may be used, isinserted in the fabric a sufficient distance from the free edge to givea body of material of enough width to prevent ripping or tearing. Afterforcing the tyne through the fabric until the cross member is inengagement therewith, the point of the tyne is in troduced through theopening 5, and pushed between the edge 7 and flap 4. This flap i willguide the tyne and will hold it in place against the inner surface ofthe'roller. The cross member of the fastener is preferably of less Widththan the opening or slot 5, as shown, so that the fabric may be actuallyforced into such slot, as shown in Fig. 4L, and engage with the edges 6and 7. The fabric will now be held in position and may be used in thismanner, the upper edge of the cross member of the fastener engaging withthe edge 6 of the opening 5, such edge serving as an anchorage toprevent the fastener from pulling out of the opening. The fastener willbe held in position to engage the fabric with the edge G by the elasticengagement of the flap et with the tyne of the fastener'. l prefer,however., to bend the fabric over to the position shown in Fig. 2 sothat the bight of the fabric will engage with the upper edge of thecross member l0 and will exert stress upon the fastener in the directionto force it toward the edge 7 and will keep the fastener seated. Thefabric will thereby be pinched between the lower edge of the crossmember and the edge 7 and will be effectively held in such position.This arrangement I prefer to that illustrated in F l, for should thefabric be entirely unrolled from the roller there will be less danger ofthe fasteners coming out. of the openings. It will be apparent that thefastener will be secured even if the fiap does not engage with elasticpressure upon the tyne, or if it engages with but j slight pressure thetyne will be retained in position by the stress exerted upon it by theengagement of the fabric with the upper edge of the cross member.

In Fig. l the roller is illustrated with the extension portion 12, whichis secured to the rest of the roller by the wooden rod 13 in the usualmanner, so that the length of the roller may be adjusted. The roller isheld in its extended position in the usual manner.

The shape of the fasteners may be varied as desired. Fig. 7 shows amodification in which two tynes are employed. The length of the crossmember may be such that both tynes will lie within one opening', or itmay be made longer so that a tyne will lie in each contiguous opening.In the modification shown in Fig. 8, more than two tynes are employed.In this modification a single fastener may be employed with each roller,there being a tyne for each opening 5.

A large number of advantages are apparent by my invention. The openingsor slots 5 being removed from the edge 3 pro duces a continuous edge forsoldering, which makes the roller cheap to manufacture and does notreduce its strength. The flaps Li serve not only the purpose of holdingthe fastenings in position, but they serve as a means for guidinv thetyne into place and prevent any possi ility of the tyne coming intocontact with the springl in the roller. Another important feature of myinvention lies in the ability to adjust the fabric along the length ofthe roller. This is important as the fasteners may not be adjustedexactly in the proper place upon the fabric. `When this happens, it isunimportant, as the fasteners may be adjusted in any position Within theopenings 5 after the fabric is in the position shown in Fig. l. It is tobe understood that to permit this to be done the openings 5 should belonger than the cross members l0.

An advantage of my invention over the ordinary grooved roller is thatthe roller is much stronger, as it is practically solid. A. greater'advantage, however, resides in the fact that the fabric does not have tobe drawn through a groove from end to end. The absence of the groovepermits a roller of much rounder shape to be made and makes it much moreeasy to form it of definite and standard size. The shape of the rollercannot be changed, and it cannot be otherwise strained or injured duringthe insertion of the fasteners and in the subsequent handling. Thespringv tongue 4e permits fabrics of any thickness to be used. Theinvention is particularly applicable to attachment of canvas awnings torollers, the thick fabric beingV practically secured in yplace by thefasteners.

By my invention the fabrics may be attached to the rollers without theneed of tools. all of the fasteners may be attached in place wit-houtturning the fabric over. The fasteners may be properly spaced and placed`by first ruling a pencil line at the propervdistance from the edge ofthe fabric. of the fasteners may be inserted in the fabric All beforethey are inserted into the' openings, or the fasteners may be insertedthroughthe fabric and openings successively, whichever is mostconvenient. The fabric may be creased before the fasteners are insertedin place; the line of crease serving. to guide the operator inintroducing the fasteners in proper position.

The modiiication illustrated in Figs. 9 and 10 employs the same form of.fastener` All A particular advantage lies in that opening analogoustothe opening 5, is produced, such opening being formed by parallelslots or slits 15 and 16, the material between the slits being struckoutward to form a band 17; the distance that the band 17 is struckoutward is substantially the same thickness as the tyne 11 of thefastener. The fastener is inserted through the fabric as described inconnection with the embodiment already described, the tyne going intothe opening through the slits 14 and 15 and underneath the band 17. Thefabric in engagement with the lower edge of the cross member 10 isforced int-o contact with the edge of the band, at the slit 15. The freeend of the tyne may be left in position without changing it or it may bebent down against the roller, or upward over the band, as desired. Thismodification of my invention is illustrated for the purpose of showingan arrangement which may be adjusted longitudinally upon the roller.

Figs. l1 and 12 show a modification of the manner of attaching thefastener to the fabric. rIhe flap 18 of fabric or other material isattached to both the sides of the edge of the fabric by gum or by othermeans, the tyne of the fastener passing through the opening of the flap.The fastener is then attached to the roller in the manner described.

Fig. 13 shows another modification in which the tyne of the fastener isbent back under the cross member. The opening in the roller is a simpleslot, the fabric being clamped or pinched between the tyne and crossmember, and against the roller. The tyne may be elastic or not asdesired. It will be apparent that the tyne in this construction has thesame function as the flap 4 already described. The roller in thismodication has walls that are somewhat thicker than those alreadydescribed. The thickness of the walls is immaterial to the properfunctioning of the fastener.- The tyne of the fastener is curved so thatit will engage with the inner wall of the roller, so that the fastenerwill be guided when inserted and the tyne will not come into engagementwith the spring of the roller.

It will be apparent that the fasteners and roller described embrace astructure in which there are two elements, one with at least two walls,and the other with at least one wall, one member being grasped betweensuch two walls. The member with the two walls may be the roller, asillustrated in Figs. 1 to 12, or it may be the fastener as illustratedin Fig. 13. If the parts be so modified that both have two or morewalls, the same function would result.

In placing the fastening shown in Fig. 13 in position, the tyne ispushed through the fabric until the cross member rests upon it. The tyneis then inserted in the slot and brought to bear against the inside ofthe l 'can be carried out in other ways.
